Company

CoreWeave is The Essential Cloud for AI™, delivering a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence.

What you will do

• Design data models and APIs that capture the complexity of datacenter infrastructure, including devices, connectivity, cabling, power, cooling, and spatial relationships across racks, rows, and floors.
• Build high-throughput API services in Go (gRPC, GraphQL, and/or REST) that support the data density and interaction speed the frontend demands.
• Develop the backend architecture from the ground up, including service structure, data access patterns, caching strategy, and API contracts.
• Integrate with internal/external systems and data sources that feed infrastructure planning, ensuring the platform reflects real-world state and planned builds accurately.
• Handle deployment and operational infrastructure for the services you build, including Kubernetes manifests, CI/CD pipelines, observability, and reliability practices.

Requirements

• Strong proficiency in Go.
• Deep experience with relational databases, specifically PostgreSQL and CockroachDB.
• Experience designing and building APIs (gRPC, GraphQL, and REST) with attention to type safety, pagination, caching, filtering, and error handling.
• Experience of performance optimization on the backend.
• Familiarity with authentication, authorization, and backend security best practices for internal tooling.
• Experience owning deployment and operations for the services you build: Kubernetes, CI/CD pipelines, monitoring, alerting, and incident response.
• 5+ years of professional backend engineering experience, with meaningful senior-level ownership of production systems and the data layers behind them.
• Strong communication skills.
• Strong sense of ownership for the systems you build and the people who depend on them.
• This position requires access to export controlled information. To conform to U.S. Government export regulations applicable to that information, applicant must either be (A) a U.S. person, defined as a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (green card holder), (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, (B) eligible to access the export controlled information without a required export authorization, or (C) eligible and reasonably likely to obtain the required export authorization from the applicable U.S. government agency.

• Experience building systems that handle complex graph-like or hierarchical relational data (asset trees, network topologies, dependency graphs).
• Exposure to Infrastructure-as-Code, Terraform, or GitOps workflows.
• Experience with event-driven architectures, change data capture, or audit logging for compliance-sensitive systems.
